Wow this is really amazing to see first time to see this kind of revolver A 1858 remington revolving rifle or cattleman's rifle,, thanks for posting this weapon sir,, i really like it and the barrel is really cool its so high.. it this gun still in this century..

Id say youre are spot on, Ive never seen one without a straight stock and corncob fore end but on doing a bit of searching it looks like three variations were made and the one pictured is a Model 1906 Expert
